To all whom it may concern: V

Be it known that I, ALFONS MosoA, a citi- Zen of the United States,residing at Norfolk, in the county of Norfolk, State of Virginia, haveinvented certain new and useful Improvements in Ice-Shaving Machines;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same;

This invention relates to ice shaving inachines and particularly to atype adapted for finely shaving ice for use at soda fountains andthelike.

The object of the invention resides in the provision of a machine of thecharacter named embodying improved constructionwhereby the operation ofsame is rendered rapid and effective and machines of this 7 typesimplified.

lvith the above and other objects in view the invention consists in thearrangement and combination of parts to be hereinafter more fullydescribed and particularly pointed out in the appended claims.

In describing the invention in detail reference will be had to theaccompanying drawings wherein like characters of reference denotecorresponding parts in the several views, and in 'which Figure 1 is aplan view of an ice shaving machine constructed in accordance with theinvention;

Fig. 2, a side'view of what is shown Fig. 1;

Fig. 4, an end view ofthe machine;

Fig. 5, a partial longitudinal section;

Fig. 6, a section on the line 66 of Fig.

Fig. 7, a section on the line 77 of Fig. 2;

Fig. 8, a section on the line 8-8 of Fig. 1, and

- Fig. 9, a view in elevation of the thread block.

Referring to the drawings the improved ice shaving machine is shown ascomprising a casing A formed of a bottom section 10 supported upon legs11 and a top sect1on 12 hinged to the bottom section at one side edgeandprovided with ahandle 13 whereby said top section may-be raised toafford ac- "cess to the interior of the casing for the purpose offilling the latter with ice. One end a of the casing A is closed byahead 14 having a depending discharge mouth 15 through which latter theshaved ice is delivered into a suitable receptacle. The outer side ofthe lower end of said discharge spout embodies a separate plate 15hinged at 16 and de tachably fastened at 17 whereby access to theinterior of the spout may be readily had for adjustment of the knives tobe presently referred to.-

Rotatably mounted in the center of the head 14 is a shaft 16 which hasfixed on the inner end thereof a knife disk B upon which is mounted inasuitable manner a plurality ofradially disposed knives 17, the disk Bbeing provided with openings 18 through which the knives 18' projectrespectively. The disk B is further provided with an extended hubportion 19 having arms 20 and secured to the disk B in radial alinementwith one or" the arms 20 is a wing 21 adapted to sweep the interior ofthe head 14 during the rotation of the disk B. The periphery of the diskB is provided with teeth 22 for a purpose that will presently appear,the casing A being provided with an opening in its side wallat a givenpoint through which a gear 23 projects, the teeth of the latter meshingwith the teeth 22. The gear 23 is'fiXed upon a shaft 24 journaled in abearing 25 formed integral with the head 14. Also fixed uponthe shaft 24at the end thereofopposite the gear 23 is a gear 26which meshes with agear 27 attached to a spindle 28 which latter is rotatably mounted upona. stub shaft 29 carried by the head 14. The spindle 28 is adapted to berotated in any suitable manner, either by hand or by suit- I ableconnection with a source of power.

Projecting laterally from the head 14 is a bearing 30, while anotherbearing 31 pro-. jects laterallyfrom the opposite end of the casing Aand alines with the bearingv 30. These bearings 30 and 31 support theterminals of a tubular member32 which is provided on its under side.with a longitudinal slot 33. Disposed within the tubular member 32 androtatably mounted in the bearings 30 and 31 is a screw 34 the purpose ofwhich will presently appear. Fixed on the end of the screw' 34 adjacentthe head 14 is a sprocket wheel 35 which alines with a sprocket wheel 36fixed on the shaft 16, and traveling on the sprocket wheels 35 and 36 isa sprocket'chain 37 whereby the rotation i sleeve 43 is a controllinghandle 52 end of'which latter is secured to the 3S and the other endthereof to a fixed part 10. The disk 38 is provided with a lateralextension 11 which projects through a slot 42 in the casing A and inwhich slot the extension i1 travels during movement of the disk ihe freeend of the extension n terminates in a sleeve 13 slidable on the tubularmember This sleeve 13 has an opening le in the bottom thereof whichregisters with the slot 33 in the member 32, said opening 1% beingsurrounded by a skirt t5. h'lovably mounted in the opening 14; is ascrew block 16, having a depending portion 17. This depending portion 17is provided in its'outer face with a groove d7 in which is slidablymounted one arm of an 'L-shaped member 4:8, said arm having threadedtherein a bolt 49 which projects through a slot 50 in the dependingportion 17. Also threaded on the bolt 19 is a nut 51 which bears againstthe inner side of the portion at and whereby the L-shaped member 4-8 maybe clamped to the portion d7 in a desired adjustment. The other arm ofthe L-shaped member carries an adjusting screw 52 which is adapted toengage the bottom edge of the portion 47 to limit the upward movement ofthe L-shaped member during adjustment of the latter relative to theportion $7. The bolt 19 also extends through a slot d9 in a dependingarm 50 formed integral with the sleeve d3. The screw block %6 isnormally held out of operative relation to the screw 3 1 by means of aspring 51 mounted in the slot 49 and bearing at its lower end againstthe bolt 4:9 and at its upper end against an end wall of the slot 19.Pivoted against the outer side of the with a bottom extension 53 whichoverlies the arm 50. This extension 53 is provided with a slot 5 1through which the bolt 49 also projects. The slot 54 is so shaped thatwhen the upper portion of the handle 52 is moved to its limit away fromthe head 1% the wall of the slot 5e will coiiperate with the bolt i9 tomove the thread block 46 into operative engagement with the screw 34:and

thus connect the sleeve as with said screw 7 so that the rotation of thelatter will move the disk 38 toward the disk B and force the icedisposed between said disks against the disk B to be operated upon bythe knives 17-; Then the upper portion of the handle 52 is moved apredetermined distance to ward the head 1% the bolt 49, owing to the.

shape of the slot 5%, is released to the indisk 1 In order providedfluence of the spring 51 and the'thread block act and return the disk 38to the limit of its movement away from the disk B.

.lnorder to automatically effect the disengagement of the screw block 46from the screw when the disk 38 has moved-apre determined distancetoward the disk B there is formed on the bearing 25 an extension 55 inwhich is adjustablythreaded a tripping member 56 adapted during theforward movement of the disk 38 to engage the .extension 53 of thehandle 52 and rock said handle to effect disengagement of the threadblock i6 from the screw 34; in the manner previously described.

to hold the disk 38: at the limit of its movement toward the disk 13against the influence of the spring 39 so that small pieces of ice, ifany, can be cleared away there is mounted on the head 14: a spring latch57 adapted to engage over a nib 58 on the sleeve s3 just as the threadblock 16 is disengaged from the screw 3%. By tripping the latch- 57 itwill be obvious that the disk 38 can be returned to the limit of itsmovement away from the disk B under the influence ofthe spring 39, r

In order to hold the ice against the action of the knives 17 there ismounted upon the inner wall of the casing A a longitudinal wing 59 whichslides, in a recess 60 formed in the disk-38.

Assuming the disk 38 to be at the limit of its movement away from thedisk 13 a desired supply of ice to be shaved is deposited in the casingA between the disks 38 and B. This disk 13 is then rotated'in the mannerpreviously referred to which will result in rotation ofthe screw Thehandle 52 is then operated to engage the thread block 16 withthe screw3% when the disk 38 will be fed toward the disk 13 and the ice forcedinto engagement with the knives 17. hen the disk 38 almost reaches theknives 17 the extension 53 willybe engaged by the member '56 and the'thread block as disengaged from the screw-34:. At

the same time that this takes place the latch 57 will engage over thenib 58. Upon'tripping the latch 57 the disk 38 will be moved wear of thethread block 46.

What is claimed is 1. In a device of the class describedthe combinationof a frame, a threaded shaft;

rotatably mounted onv the frame, a member mounted for movementlongitudinally-cf the shaft, a thread block slidably mounted onthemember for movementlinto and out of engagement with the threads of theshaft,

it will be apparent that -the bolt,

spring means normally holding the thread block out of engagement withthe threads of the shaft, a lever pivoted on the member, connectionsbetween the lever and the thread block whereby the movement of saidlever in one direction will operate the thread block into engagementwith the threads on the shaft to effect movement of the memberlongitudinally of the shaft, and means on the frame for engaging thelever when the member has moved a predetermined distance to rock saidlever in the opposite direction and release the thread block to theinfluence of said spring means.
